I was having the same problem with my HP Pavillion dv4400 Notebook - HL-DT-ST DVDRAM GSA-4084N error code 39 / driver is corrupt

I deleted the upper and lower filters as ssuggested by someone here in this forum and It worked.

I've never loaded the LightScribe CD that came with this Laptop. I did it shortly after I deleted the filters. To find out the drivers for HL-DT-ST DVDRAM GSA-4084N are on the LightScribe disk. Instal and click on update.

My suggestion is to update drivers from LightScribe first if that dosent work delete the filters.

My notebook is working great!

The regedit fix worked for me!

(Although there was no "lowerfilter" item for me to delete)

Thanks!

I thank Monika Rodgers and Damien Simonetti for sharing very useful info on this forum. I am using HP Pavillion dv6000 in which i faced problems with "HL-DT-ST DVDRAM GSA-4084N" error code 39 / driver is corrupt. I tried to uninstall and rebooting my dv6000, obviously it did not work. So, I followed the following steps as suggested Monika:
(1) System Backup (2) Data Backup.
(3) Right click Mycomputer => Properties => Hardware tab => device manager (missing driver will have yello/black mark" (4) right click on the device and uninstall it. (5) start => run regedit . Go to the folder path as shown in my attachment ie HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
(6) Carefully delete "upperfilter" and "lowerfilter" items.

Well, this is continuation for my previous mail. After deleting "upperfilter" and "lowerfilter" close the window. Reboot the system. Just like magic the "HL-DT-ST DVDRAM GSA-4084N " CDROM firmware will find its lost driver. Please refer the attachment with this mail, which is after I have deleted the "Upperfilter" and "lowerfilter"

thanks to the forum.

I tried the solutions posed in this post, including the HKEY mods, and remove / reinstall drive, etc. All attempts were unsuccessful until I found this alternate post:

...which points to this original MS post:

The MS post includes the HKEY fix, but it also includes a link to the MS FIXIT utility. It was the utility that finally did it for me. MS finally scores one back, I suppose...

The Regedit process is simple. I had to call tech support like Monika... Goto "run" in windows (vista/xp) then type "regedit". Once the program is loaded, look at the attachment I have provided. Open the folders shown and delete the "upperfilter" and the "lowerfilter" items in folder named
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

These items will show up in the right hand side. In the example/attachment I have provided, I have already deleted these items. This porcess will fix the driver / failure to load / failure to start problem / error with this DVD Player.

Thank you for posting this info.  I deleted the upper and lower filters from the folder displayed in the attachment.  After I did this, I had to uninstall the DVD drive in the Device Manager which followed me Scanning for Hardware Changes which immediately got the DVD drive working again.  I really appreciate the info.
